spin [16.1K]

answer:

$B. \: 2$

explanation:

$- x + 8 > 6 \\ subtract \: 8 \: from \: both \: sides \\ \\ - x > - 2 \\ divide \: both \: sides \: by \: - 1. \: since \\ - 1 < 0 \: the \: inequality \: direction \\ changed. \\ \\ x < \frac{ - 2}{ - 1} \\ \frac{ - 2}{ - 1} = 2 \: can \: be \: simplified \: as \: 2 \: by \\ removing \: the \: negative \: from \\ numerator \: and \: denominator. \\ \\ x < 2$
